Description

Rieker Ball Bank Indicators reflect the operating procedures of Federal, State, and local roads and highways, based upon the “Speed Zone Theory” and “85th Percentile Speeds”, which is adapted by the American Association of State Highway and Transportation Officials (AASHTO); Institute of Transportation Engineers (ITE) and as defined in the Federal and/or State Manual of Uniform Traffic Control Devices, (MUTCD). Rieker indicators have been the ball bank standard instruments used by Federal and State Departments of Transportation Nationwide since the 1950's.

   

Definition

The term "Ball Bank Indicator" refers to an inclinometer (or Accelerometer used as an inclinometer) that is used for the specific purpose of determining safe  (uniform advisory) curve speeds for horizontal curves.  It measures the overturning force (side friction), measured in degrees, on a vehicle negotiating a horizontal curve.
